SAE30 10W-30 (ACD)

Amsoil 10W-30/SAE 30 Synthetic Heavy-Duty Diesel Oil
Data Bulletin 

Product Information

Exceeds both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements. Provides outstanding performance in pre-2007 diesel engines in on-road applications as well as all model-year diesel engines in off-road apps. Also recommended for gasoline engines requiring API SL or previous specifications.

Amsoil 10W-30/SAE 30 Synthetic Heavy Duty Diesel Oil is formulated with premium synthetic base oils that exceed both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements for outstanding performance in modern and older diesel engines. Unlike conventional SAE 30 motor oils, Amsoil Heavy Duty Diesel Oil has a naturally high viscosity index and does not contain paraffin (wax). It has a low pour point and qualifies for SAE 10W, making it an all-season multi-grade lubricant with a wide operating temperature range. Amsoil Heavy Duty Diesel Oil is formulated without viscosity index (VI) improvers. This shear-stable formulation is designed to reduce viscosity loss and associated bearing and cylinder bore wear. Amsoil 10W-30/SAE 30 Synthetic Heavy Duty Diesel Oil contains premium additives with a high 12 TBN to neutralize acids from blow-by, exhaust gas recirculation (EGR) and high-sulfur diesel fuels. It helps protect against damaging piston deposits, ring sticking and sludge.

Amsoil ACD is recommended for diesel engines, gasoline engines and other applications that require any of the following worldwide specifications:

  • API CI-4+/CH-4/SL, CF, CF-2
  • Global DHD-1
  • ACEA A3/B3, E3, E5
  • JASO DH-1
  • Mack EO-M, EO-N
  • Detroit Diesel 93K214
  • Caterpillar ECF-1a, ECF-2
  • Cummins CES 20076/20077/20078

  • Mercedes Benz 228.1/228.3/229.1
  • MAN 271/3275
  • MTU Type 2
  • Ford WSSM2C921-A


Amsoil ACD is compatible with conventional and synthetic motor oils, however, mixing Amsoil ACD with other oils will shorten the oil life expectancy and reduce the performance benefits. Amsoil does not support extended drain intervals where Amsoil ACD has been mixed with another product.

Aftermarket additives are not recommended for use with Amsoil ACD.


  • Amsoil Synthetic 10W-30/SAE 30 Heavy Duty Diesel Oil (ACD) is recommended for extended drain intervals in engines that are unmodified and in good operating condition.
  • Diesel Engine Service: Three times (3X) OEM* recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first. Drain intervals may be extended further with oil analysis.
  • Gasoline Engine Service: Two times (2X) OEM* recommendation, not to exceed 15,000 miles or one year, whichever comes first.

*Operating conditions and drain intervals for severe and normal service are defined by the OEM. Refer to your owner’s manual.

Note: Extended drain intervals are not recommended when using biofuels containing >10% ethanol or 5% biodiesel (B5). Follow OEM drain intervals or extend drain intervals with oil analysis.
